Gese, hasn't the censor thing run its course. When do we start
discussing amplifiers?

Hey Doug, there are a number of people who most likely need to get it
out of their system. There is also some history explaining how we got
to this point. My guess is that this part of the discussion will blow
over in about a week. Let's be a bit more patient.

I have plans to build my first amplifier using a 4CX250B. I have the
tube, socket, enclosure, and some parts. Maybe we can build it right
here on the reflector! I'm looking forward to the education!

### After 15 x hb linears..imo.. why even mess with a 4 x
4CX250B linear ???

### 4 x sockets... 4 x chimney's.... 4 x tubes 4 x parasitic
suppressor's..... regulated rx/tx bias supply...... reg
screen supply etc.

### You don't put 4 x engines under the hood of a car. IMO...
if one tube doesn't do the job... select a bigger tube.


### These YC-156's [and YC-172's] are a huge bang for the
buck. 200 w drive = 10kw + out. No socket required. $400.00

### after messing about with multiple tube linears in the
past... and also trying to balance the airflow through all of
em... and also trying to adjust individual idle currents, and
also trying to balance the drive levels into each tube.... I
swore I'd never build anything but single tube linears ever
again.......... best thing I ever did.

### trbl shooting a 4 x tube amp at times is no fun either.

### If u attempt a 4 x tube linear.... make sure you have at
LEAST 4-6 new tubes, or known good ones.

### My conclusion after doing this since 1974 is it's just as
easy to build a big amp... as a small one.

Later.... Jim VE7RF

Censoring anyone who questioned Tom's dicta was part of AMPS for a bit over 9-years, so some discussion about what we endured is in order, Doug. cheerz.

I think its unfortunate how most ham radiogroups have evolved in to
some kind of cult worship society or worst product worship society.
As I see it, guru worship with a large pack of yippy lap-dogs takes the cake.

It seems some forget what the purpose and aims all these groups are
for, that is that they here to foster the spread of knowledge.
To me, passing along what we OTs have learned is worthwhile -- despite the hairpulls with censors and "experts"..

What we have on many ham newsgroups, are some very well meaning
characters who go beyonds the stated aims of groups.
Well meaning people are not into being worshiped.

The most annoying thing about ham groups is the request for a
callsign. Now since when do you need a callsign to use the internet?,
or when you need to show your drivers license to join a car
discussion group? This form of moderation is under the guise of
wanting to control spam, which is nonsense.
Indeed. After Bill was gone, Tom ran amuck.

To me the content of the
post to newsgroup should determine its value. Why many want callsigns
is so that they can indentify the person posting for personal attacks
in most cases.

If technical editing is required why not let the members of the group
select a few technical moderators, if 10 agree the post is garbage
then it can get deleted.
If a post contains technical garbage, better to let the members who know better critique its author.

I'm automatically suspicious of a poster without a callsign unless
they come right out and say why they don't. Most hams are proud of
theirs and anyone who isn't is... suspect. Do you have one?

Bill,

I don't have one now, and haven't since the early 80's when I used it for a
whole 9 monts if that (Novice). However, I think everyone that was on the
Amps mailer knows what happened in my case so it's kind of a moot point.
I'll get one again if the rule changes that supposed to happen eventually
do, and to my liking. I made a promise back then in the 80's due to a good
friend, and I've kept it up to this date.

Best,

Will
